To all wlw/m t may conce/m.;

Be itknown that I, JOHN P. NORDSTROM, a citizen of the United "States, residing at Brooklyn, in the county of Kings and State of New York,'ha`ve invented certain new and useful Improvements in Piles, of whichlthe clear,y and exact L dc-i.

or strata. When piles are insertedinto mud.

quicksand, lor ya similar'soft or boggymass,

the mass packs around'the pile and supports it, partly due to the skin or surface friction of the mass upon the surface of the pile and partly due to the area yoit'y `the pile which bears uponthemass. 1 i

An object of'this invention to provide a pile Whichwhen inserted into soft bottoms or strata will have an increased bearing power,` and which may be sunk or driven in the usual manner. A further and more particular object is to provide a pile having a maximum possible bearing area and surface friction, which' will be strong, simple, effective, durable, inexpensive and have greater sustaining power. y and advantages will Lbe app-arent from the following description andthe novel features of the invention will be particularlyT pointed out in claims.

In carrying the invention into practice, I increase the bearing area and surface friction by means of transverse lagging which is suitably secured to the sides of the usual piles, prior to sinking or drivingv them, the details of the lagging and its manner of attachment being more particularly pointed out in connection with the following description of specific applications of the invention.

In the accompanying drawing:

Fig. 1 is a front elevation of a pile con structed in accordance with this invention.

Fig. 2 is a side elevation of a section of the pile.

Fig. 3 is a section of the same taken substantially along the line a-a of Fig. 2.

Fig. 4 is an elevation of a detail.

Fig. 5 is a perspective of the section shown in Fig. 2.

Other objects Fig. 6 is an elevation of a section of a pile manner of attachment and,

is a section of the same taken along the line b?) ofFi'gp.' u l "In the kembodiment illustratedin Figs. .l to 5","thebody portion/l of lthe. pile, which may ,be `of any suitable material such as illustrating a modified forruof lagging and y wood`reinforced concrete, etc., is provided with a driving point '2.` Notches 3 are pro vided on oppositesides of Athebody portion and'opposite one anothergand are arranged in spaced relationl (about `every three `feet) along the lengthofthe part` of the body portionjwhich is driven or sunk into' the soft strata or bottom.1 Auxiliary bearing or lagging-strips 4 are/disposed in the notches to extend transversely of the body portion,-

one ortwo oi' the strips nearestthe driving point vbeing preterablyeshorter than thel -`r`others, `So as to facilitate ythe, penetration yof the pile. The' strips may be temporarily held within the notches by spikes 5 or simi,- lar and suitable fastening means. Stirrups 6 which may be of metaly having a somewhat triangular shape embrace tliefproject-y ing ends of thestrips with a portion such as the base kof each stirrup passing over the upper edges of thestrips 'andwith the ends or apex of Aeach ystirrup,dependingalong the sides of the bodyportion. verging arms or sides of the stirrups are providedwith loops or eyes 7 which are super posed, and ra single bolt 8, passing censuperposed loops or eyesatr each side of the The conbody portion, serves to anchor the -stirrups M to the bodypprtion, Thewstirrupsqconfine thelagging 'or strips Within the notches, prevent movement of the strips lengthwise of the body portion, and prevent breaking olf of the strips during the driving or sinking operation. Staples 9 may be passed over the base of the stirrup and into the body lportiony where the latter is of Wood, to prevent any movement of the base of the stirrups away from the body portion.

In the embodiment illustrated in Figs. 6 and 7, the strips l() comprise angle irons or members which are secured to opposite faces of the body portion by bolts 12 passing be tween the angle members and through the body portion of the pile. have both ends threaded to receive clamp- The bolts may ing nuts and be cast in the body portion at the time the pile is cast, but preferably pipe sleeves 13 are cast in the body portion of the pile through which sleeves ordinary bolts may be passed when the angle members or strips are attached. The vangle members are preferably provided with 'apertures ltelongated longitudinally of the members in order to compensate for any small inequalitites in the placing of the bolts or sleeves in casting the pile body portion. The-'strips lare held against displacement from ythe body rpor-` tion bythe bolts and by the frictionof lthe strips against -the sides of the body 'portion when the strips are firmly clamped thereto.

The uppermost l'aggingfjshould vbe 'lat a distance from thetop which will permit it .to comebeneath the Vways ofthe driverwhen the pointy is lresting upon the upper surface of the bottom or strata. Thewlagging not only increases the bearing surface of the pile Vbut also increases the vsurface friction due to the increased area in contact with the mass in which it is placed, withl a resulting net increase inbearing power kof the pile. The sides of the stirrups may, after theyare assembled upon tli'e -body portion, Ibe bent as lat 6a to tighten Ythem slightly.

ItA -willbe obvious that various 'changes in the details and arrangements of parts in the embodiments iillustrated and described, may be made b'y those skilled inthe art `within the principle and scope 'of rthe invention. n

I claim: p

l. A pile comprising an elongated body portion, a pair of auxiliary bearing strips disposed on opposite sides ofthe body portion land opposite rone "another, and common means for securing both strips against movement end'wise of the body'portion.

l2. A pile comprisingan elongated body portion havingiiotches on opposite ksides thereof and opposite one another, auxiliary v' bearings strips disposed in said notches to extend transversely to thebody portion, and means for securing the strips againstinovement endwise of the body portion and within the notches.

3. A pile comprising an elongated bodyv .my signature.

'endwise of the body portion.

4. A pile comprising an'elongated body "portion, a pair of auxiliary beaiing strips disposed on opposite sides of the body portionand opposite one another, and stirrups passing over the ,ends of both of the strips and anchored to ythe body portion below the strips 'to @prevent lendwi'se movement of the strips lalong the'body portion.

5. vA 'pile Acoinprisiiig an elongated body portion, Ia 'pair of auxiliary bearing strips disposed kon oppositesides vof the body portion and opposite'one another, 'stil-rups passing over Ethe ends of both 4,of the strips, and-a single bolt passing through the body portion and lower 4ends lof the' stirrups for anchoring the strips to the body portion.

6. A pile g'comprising` an .elongatedbody portion, an auxiliary lbearing strip extending transversely of and disposed against a face `of thebody portion,yand stirrups pass- .ing'ove'rthelextending ends of the strip and anchoring to the body portionfbelow the strip.

7. A pile comprising an `elongated body portion having notchesjon opposite sides thereof and opposite one another, auxiliary bearing strips disposed in said `notches to extend .transversely to lthe body portion, means joining the corresponding projecting ends of the strips for confining the strips within the notches. y

8. A pile comprising an elongated body portion, an auxiliary bearing member extending transversely of the body portion, andan anchoring element engaging with the member .and anchored to'the body portion below the member for y,preventing upward endwise move'inentof the member along the f body portion.

In witness whereof, lvI `hereunto subscribe JOHN P. NORDSTROM.
